Abstract

Powder-based additive manufacturing (AM) is an important technology in fabricating complex 3D products. In powder-based AM, a powder deposition system plays a key role in determining the resolution, density, and properties of printed parts. An acoustic-actuated particle deposition approach, which utilizes acoustic waves to actuate a glass nozzle, enables the deposition of particles in a cost-effective way. However, the capability to programmably deposit different particles using acoustic waves has yet to be fully demonstrated. Herein, a selective particle deposition approach via acoustic modulation for muti-material AM is demonstrated. Sequential and parallel depositions of two types of particles by modulating the signal inputs and resonant frequencies of piezo transducers are demonstrated. An AM process is demonstrated by integrating this acoustic-actuated particle deposition approach with a heat-curing mechanism. Several products from this system are produced as well. It is expected that this particle deposition approach can be used in a wide spectrum of applications, such as direct manufacturing of multi-functional materials/devices.
